A

Amylose and amylopectin

44
Q

Amylose

A

Straight chain polymer

45
Q

Amylopectin

A

Branched chain polymer

46
Q

Bonds that hold monosaccharides together

A

Glycosidic bonds

47
Q

Type of reaction for kinase

A

Phosphorylation and phosphate

48
Q

Type of reaction for dehydrogenase

A

Dehydrogenation NAD and FAD

49
Q

Step one and three of glycolysis

A

Phosphorylation
Kinase
ATP

50
Q

Step two of glycolysis

A

Isomerization

Isomerase

51
Q

Gluconeogenesis

A

Pyruvate to oxaloacetate to phosphoenal pyruvate

1-3 irreversible: need phosphotase to reverse

52
Q

When and why is lactate produced in muscles ?

A

When energy production is required faster than our bodies can deliver oxygen
Pyruvate is reduced to lactate to break down glucose
So high levels of lactate are produced

53
Q

Overall Rxn of pyruvate before TCA cycle

A

Oxidative decarboxylation to produce acetyl CoA

54
Q

ATP difference for glycolysis and gluconeogenesis

A

Gluconeogenesis uses ATP to regenerate glucose so there is a loss of energy

55
Q

Glucose:pyruvate

A

1:2

56
Q

Step six of glycolysis

A

Phosphorylation and redox rxn

Kinase and dehydrogenase

57
Q

Step nine of glycolysis

A

Dehydration

58
Q

Steps 3 and 6 of TCA cycle occur where?

A

Intermediate space

59
Q

Step 1 rxn of TCA

A

Condensation

60
Q

Step 2 rxn of TCA

A

Isomerization

61
Q

Step 4 rxn TCA

A

Decarboxylation

62
Q

Step 7 rxn TCA

A

Hydration

63
Q

Two mechanistic theories for electron transport

A

Chemiosmotic coupling: high H causes to enter ATPase and produce ATP

Conformational coupling

64
Q

Step one B oxidation

A

Fatty acid reacts with CoA to produce acyl CoA

Flows through outer membrane

65
Q

Step 2 B oxidation

A

Splits apart in intermembrane
Acyl reacts with carnitine to produce acylcarnitine
Flows into matrix

66
Q

Step 3 B oxidation

A

Splits apart

Acyl reacts with CoA to produce AcylCoA

67
Q

Common product of fatty acid anabolism

A

Palmitic acid

68
Q

Propionyl CoA

70
Q

Overall purpose of steps 5-8 TCA

A

Reproduce oxaloacetate
